Oral cancer is one of the most common malignant tumors in the head and neck,with approximately 90%of oral cancer being squamous cell carcinoma.Oral squamous cell carcinoma(OSCC)has a high degree of malignancy and a poor prognosis,posing a serious threat human health.The occurrence and development of OSCC are relatively complex,influenced and regulated by multiple factors and levels,and the molecular mechanisms is currently not fully understood.Long non-coding RNA(lncRNA)can exert various biological functions by regulating gene expression and function at the transcriptional,translational,and post-translational lev-els.The occurrence and development of OSCC involve the abnormal expression of lncRNA.Therefore,this article reviews the relevant research on the function and molecular mechanisms of lncRNA in OSCC,in order to provide a reference for future studies.

Objective:To evaluate the therapeutic efficacy of combined therapy with a speaking valve and transcranial direct current stimulation (tDCS) for dysphagia in stroke patients post-tracheostomy.Methods:This retrospective case-control study enrolled 120 stroke patients with post-stroke tracheostomy-associated dysphagia, admitted to the Department of Rehabilitation Medicine at Huai′an Second People′s Hospital. Participants were randomly allocated to either a control group [45 males and 15 females, aged from 46 to 78 (65.78±8.68) years]receiving tDCS and conventional rehabilitation or an intervention group [41 males and 19 females, aged from 46 to 79 (66.32±9.18) years]receiving tDCS plus speaking valve therapy, with 60 patients per group. Swallowing function was assessed before and after a 3-week intervention using the Standardized Swallowing Assessment (SSA), Water Swallowing Test (WST) grading, Functional Oral Intake Scale (FOIS), and Swallowing-quality of life score (SWAL-QOL).The SPSS 22.0 was used for statistical analysis.Results:The intervention group demonstrated a significantly higher overall treatment response rate than the control group [95.0%(57/60) vs 78.3%(44/56), χ2=-6.056, P<0.001]. Post-treatment, the intervention group showed significantly greater improvements, as evidenced by a lower SSA score (21.50±1.82 vs 24.92±1.42, t=-11.480, P<0.001) and superior WST grades (observation group: 45 cases at grade 1, 12 cases at grade 2, 5 cases at grade 3; control group: 33 cases at grade 1, 11 cases at grade 2, 16 cases at grade 3, Z=5.484, P<0.001). Furthermore, the intervention group achieved significantly higher FOIS scores (observation group: 1 case at grade 1, 1 case at grade 2, 1 case at grade 4, 8 cases at grade 5, 7 cases at grade 6, 45 cases at grade 7; control group: 2 cases at grade 1, 7 cases at grade 2, 3 cases at grade 3, 4 cases at grade 4, 5 cases at grade 5, 6 cases at grade 6, 33 cases at grade 7, Z=-3.559, P<0.001) and greater improvements in SWAL-QOL scores ( P<0.001), indicating enhanced oral intake and quality of life. Conclusion:The combination of a speaking valve and tDCS effectively promotes the swallowing recovery and improves quality of life in stroke patients with post-tracheostomy dysphagia. This combined modality represents a promising and effective therapeutic strategy for this patient population.

Aim To explore the mechanisms of PM2.5 exposure exacerbating bleomycin(BLM)-induced idio-pathic pulmonary fibrosis(IFP)by regulating ferropto-sis via nuclear factor 2 related factor 2(Nrf2)/solute carrier family 7 member 11(SLC7A11)/glutathione peroxidase(GPX)4 axis.Methods Forty C57BL/6J mice were randomized into the control,BLM,PM2.5,BLM+PM2.5 and sulforaphane(SFN,Nrf2 agonist)groups,with eight mice in each group.PM2.5 expo-sures were conducted to the BLM-induced IPF mice for two weeks.The lung function was measured,and the content of hydroxyproline(HYP)in lung tissue and the pathomorphology of lungs were observed.Reactive oxygen species(ROS),malondialdehyde(MDA),ferrous ion(Fe2+)and glutathione(GSH)of the lung tissue were measured by ELISA.The mRNA and pro-teins levels of Nrf2,SLC7A11,GPX4,collagen typeⅠ(COL-1),α-smooth muscle actin(α-SMA)were measured by quantitative polymerase chain reaction(qPCR)and Western blot.Results Compared with the control group,the lung function of mice was signif-icantly reduced(P＜0.01)in the BLM and PM2.5 groups,while lung tissue showed the characteristic pathological changes of pulmonary fibrosis such as a large number of inflammatory cell infiltration,alveolar wall fracture,thickening,collagen deposition,and sig-nificantly increased HYP,Fe2+,ROS,MDA(P＜0.05,P＜0.01),genes and proteins of COL-1,α-SMA(P＜0.01);and decreased GSH,Nrf2,SLC7A11,GPX4 genes and proteins(P＜0.05,P＜0.01).The above-mentioned lesions were markedly aggravated in the BLM+PM2.5 group compared with the BLM(P＜0.05)and PM2.5 groups(P＜0.01),and were also improved in the SFN group(P＜0.05,P＜0.01).Conclusions PM2.5 exposures can exac-erbate IPF-induced IPF in mice,and the regulating of Nrf2/SLC7 A1 1/GPX4 axis and ferroptosis might be in-volved in the related mechanisms.
